Abstract
The regeneration of cirri was followed in two common intertidal barnacle species, following non-lethal predation by an intertidal teleost. While >50% of damaged Semibalanus balanoides individuals showed some degree of cirral re-growth within 16 days, this level of regeneration was not reached in Chthamalus montagui until 32 days after removal of the cirri. Full re-growth of cirri required at least two moults in both species.
